UNITED STATES PATENT OFFIC CHARLES E. ONGLEY, OF NEW YORK, N. Y.,ASSIGNOR TO GEORGE J.

SCHOEFFEL, OF SAME PLACE.

VALVE-CONTROLLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 570,045, dated October27, 1896. Application filed October 30, 1893. Serial No. 489,506. (Nomodel.)

York, have invented a certain new and useful Improvement inValve-Controlling Devices, of which the following is a specification.

My invention relates to apparatus in which the valves of a cylinder areoperated or controlled electrically, and to the construction of valvesespecially adapted for that purpose, which valves may, however, beoperated, if desired, otherwise than electrically.

In the drawings like letters refer to like parts.

Figure 1 is a sectionalview of apparatus embodying my invention; andFig. 2, an elevation of the electromagnets, showing also the auxiliaryvalves, one of which is shown. in section.

A is a cylinder having a pistonrod a. and ports or valve connections aand a and a and a, a and a leading through a channel into one end of thecylinder and a and a into the other end thereof.

B is a valve-chest annexed to the cylinder The valvestem 1) oscillatesin the valve-chest B and is provided with two heads 12 and 17 which arearranged to open the ports leading to one end of the cylinder A to admitthe pressure thereto, and at the same time to close the ports to theother end of the cylinder to exclude the same pressure, but opening thelatter to permit a vent from that end of the cylinder. The spiralsprings b and I) lie between the heads of the valve-chest and the headsof the valve-stem and are of equal tension.

y and y are vents through which the pressure is discharged.

C is a cylinder having a piston-rod 0, pro

vided with a head at one end and secured at the other to the valve-stem0 said cylinder being provided with the valves 0 and c and vents c 'and0 The valve 0 is shown in section in Fig. 2, and the valve is shown inelevation.

D and D are eleetromagnets suitably mounted and having armatures d and(1 secured to the valve-stems c and c of the valves 0 and 0*. Electricalcircuit connections extend to the electromagnet-s D and D and means areprovided to control these parts. Any of the well-known connections andcir cuit-controllers may be employed for the purpose. Pressure issupplied to the valvechest B through the supplypipe 1), and thence, asrelated, to cylinder A, and pressure is supplied to the cylinder 0through the valves 0 and 0 through the supports, which are also pipes, cand a The channel o conveys the pressure from valve to the end of thecylinder 0.

E is a lever to operate the valve by hand.

The operation of my device is as follows: The position of the deviceshown in Fig. 1 is that when the machinery is at rest, the pressurebeing equalized. erate the same electrically, I -.lose the circuit toone of the magnets D or D thus energizing that magnet and attractingitsarmature thereto, thereby operating one of the valves or c to admitpressure into one end of the cylinder 0. This pressure operates to movethe piston-rod c and valve-stem b and the heads 5 and b ,,the movementbeing, for instance, in the direction of the arrow 1. The ports a. and aare thereby opened to the pressure and the ports a and a are closed toit, the ports a and a being, however, opened to the vent y. Thuspressure is admitted into the cylinder A to move the piston-rod a in thedirection indicated by arrow 2. Making the circuit through the other ofsaid electromagnets operates in the same way to move the other valve ofthe cylinder 0 and to move the heads 6 and b in the reverse direction ofthat last described, thus opening and closing the ports of the cylinderA to move its piston-rod in the reverse direction.

The spiral springs b and b are of equal tension and operate to hold thepiston-heads b and b in the normal positions shown in Then I desire toop-.

Fig. 1, thus equalizing the pressure in the cylinder and holding thepiston-rod stationary. In operating my device any liquid or fluid underpressure may be employed, such as steam, water, and air.

The advantage of using steam or its equivalent in the cylinder 0 is,first, that it is very rapid in its operation, and, second, that whenthe steam or air is cutoff the same condenses or escapes through theports 0" or c leaving the apparatus free to be operated by hand with thelever E.

This device is particularly useful for the reason that it may be appliedto the valve of any engine without interfering With or altering theexisting machinery, and leaving the same capable of being controlledeither electrically or by hand at will.

\Vhat I claim is- In a valve-controlling device, the valve consisting ofa valve-chest having inlet and outlet ports and a valve-stem having twoheads to control said ports and two springs bearing with equal tensionupon the valvestem heads, in combination with a motor to opcrate saidvalves, consisting of a cylinder havin g operative valves and piston-rodand electromagnets in circuit having armature secured to the valve-stemsof said motor and means to control the circuit.

This specification signed and witnessed this 25th day of October, 1893.
